perform method

  1. @override
Future<BlocxUseCaseResult<BlocxPage<T>>> perform(
  1. BlocxPaginatedInput input
)
override

The business logic implementation.

Called by execute. Throw freely — exceptions are caught and converted to BlocxUseCaseFailure automatically.

Return values via success:

return success(myOutput);

Implementation

@override
Future<BlocxUseCaseResult<BlocxPage<T>>> perform(
  BlocxPaginatedInput input,
) async {
  recordedInputs.add(input);
  if (delay > Duration.zero) await Future<void>.delayed(delay);
  if (completer != null) await completer!.future;
  if (shouldFail) throw failureError ?? Exception('Paginated task failed');
  final page = source.getPage(offset: input.offset, limit: input.limit);
  return success(page);
}
